Abstract
The utility model provides an electric automobile is with electronic power assisted steering pump second grade insulator arrangement for electric automobile. The oil pump axle head that turns to the oil pump is connected through shaft coupling and the motor shaft that turns to the motor, is equipped with an insulating spacer between shaft coupling and the motor shaft, and oil pump axle head and turning to is equipped with the insulating spacer of flange between the motor, is equipped with the sealing washer between oil pump axle head and the insulating spacer of flange, turns to the oil pump and turn to to link together through the connecting screw between the motor, and it has insulating spacer to overlap on the connecting screw, turns to and is equipped with insulating shock pad between motor and the frame. The utility model discloses the insulating material proof voltage is more than 60KV, and anticorrosive and aging resistance can be good, turn to oil pump and the connection place that turns to the motor can realize sealed totally, insulating with keep apart, complete machine shock attenuation and shock resistance are strong, noise when having reduced the complete machine full load can effectively realize turning to two minor insulation of assembly, makes the whole electronic assembly protection level that turns to can reach IP67, the withstand voltage grade of two minor insulation can reach interchange 3000V.
Description
Technical field
The utility model relates to electric vehicle engineering field, specifically a kind of electric power steering pump secondary insulation device used for electric vehicle.
Background technology
Existing Vehicular electric power-assisted steering assembly does not have secondary insulating, causes the high-tension electricity in steer motor or respond to electrostatic conducting on oil pump, makes car load have the danger of band high-tension electricity.And the high pressure of new energy electric motor vehicle more than DC600V nearly, potential safety hazard is quite large.And, without secondary insulating power-assisted steering pump because of connecting between motor with oil pump be directly rigid connection mechanically, cause the concentricity because of motor and oil pump in running bad, when high rotating speed or full load, machinery noise is larger, there is relative wear between motor shaft and oil pump shaft simultaneously, have a strong impact on the service behaviour of electric power steering assembly.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of electric power steering pump secondary insulation device used for electric vehicle, to realize insulation completely between motor and oil pump and isolation.
For achieving the above object, the oil pump axle head of steering pump of the present utility model is connected with the motor shaft of steer motor by shaft coupling, is provided with axle insulating spacer between shaft coupling and motor shaft.
Flange insulating spacer is provided with between described oil pump axle head and steer motor.
Sealing ring is provided with between described oil pump axle head and flange insulating spacer.
Linked together by attachment screw between described steering pump and steer motor, on attachment screw, cover has for making the insulating spacer of isolating that insulate between steering pump and steer motor.
Insulation beam is provided with between described steer motor and vehicle frame.
The utility model compared with prior art, insulating material proof voltage is at more than 60KV, anticorrosive and ageing-resistant performance good, insulation transition piece is sunken in the front end housing of steer motor, the connection place of steering pump and steer motor can realize sealing completely, insulation and isolation, damping and the shock resistance of complete machine are strong, reduce complete machine at full capacity time noise, structure is simple, installation and maintenance are very convenient, can effectively realize the secondary insulating turning to assembly, the degree of protection of whole electric powered steering assembly is made to reach IP67, the voltage withstand class of secondary insulating can reach and exchange 3000V, substantially increase the competitiveness of product.
Accompanying drawing explanation
Fig. 1 is structure diagram of the present utility model.
Embodiment
As shown in Figure 1, the oil pump axle head 2 of steering pump 1 of the present utility model is connected with the motor shaft 5 of steer motor 6 by shaft coupling 4, is provided with axle insulating spacer 7 between shaft coupling 4 and motor shaft 5; Flange insulating spacer 8 is provided with between oil pump axle head 2 and steer motor 6; Sealing ring 3 is provided with between oil pump axle head 2 and flange insulating spacer 8; Linked together by attachment screw 11 between steering pump 1 and steer motor 6, on attachment screw 11, cover has for making the insulating spacer 9 of isolating that insulate between steering pump 1 and steer motor 6; The beam 10 that insulate is provided with between steer motor 6 and vehicle frame (not shown).
Insulating material proof voltage of the present utility model is at more than 60KV, anticorrosive and ageing-resistant performance good, good mechanical performance, effectively can ensure the high reliability of product.The profile of assembly and volume size do not increase, identical with the profile size of the former assembly not with secondary insulating.Further, after flange insulating spacer 8, sealing ring 3 damage, still connect reliably by axle insulating spacer 7 between steer motor 6 with steering pump 1 and normally work, guaranteeing the stable operation of assembly.
